Two new species of deep-sea amphipods of the genera Podocerus and Ericthonius are described and illustrated. They were collected on soft bottoms of the Bay of Campeche, SW Gulf of Mexico, at depths of 1400 to 2383 m. The two new species increase the numbers of Ericthonius species recorded to 22, the Podocerus species to 58, and the deep-sea amphipods from the Gulf of Mexico to 17 species. Ericthonius camposi sp. nov. is characterized by the cephalic lobes, gnathopod 1 basis; stridulating ridges on coxal plate of gnathopod 2 and epimera 2–3, and uropod 3 ramus. Males of Ericthonius camposi sp. nov., is most similar to males of Ericthonius brasiliensis (Dana, 1852), Ericthonius punctatus (Bate, 1857), and Ericthonius parabrasiliensis Just, 2009. Podocerus delacruzi sp. nov., is characterized by carinations on pereonites 2–4, pereonite 7 and pleonites 1–2 posterodorsally produced, uropod 2 peduncle, and telson. Males of Podocerus delacruzi sp. nov., are most similar to males of Podocerus kleidus Thomas and Barnard, 1992, Podocerus lazowasemi Baldinger and Gable, 1994, and Podocerus cristatus Thomson, 1879.
